TIRE CHAINS
CAUTION
Only certain SAE class “S” tire chains can
be used on this vehicle. Using the wrong
Class “S” chains on this vehicle will cause
damage to the vehicle. If you plan to use
tire chains/cables, you should use a tire
chain that meets the minimum clearances
for your vehicle.Use of tire chains may be prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make sure
they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions. Use a tire chain that
is designed to provide the specified space
A
between the installed tire chain1and where the
tire meets the rim
2as shown on the chart.
NOTE:
Tire chains are not permitted for use with
18 in wheels.
Wheel size Minimum space required 16 in .7 in (17 mm)
17 in .2 in (4 mm)
A tire chain that provides the specified amount of
space will provide the necessary clearance be-
tween the tire and the closest vehicle suspension
or body component. The minimum clearances are
determined using the factory-equipped tires.
Other types may damage your vehicle. Use chain
tensioners when recommended by the tire chain
manufacturer to ensure a tight fit. Loose end links
of the tire chain must be secured or removed to
prevent the possibility of whipping action dam-
age to the fenders or underbody. If possible,
avoid fully loading your vehicle when using tire
chains. In addition, drive at a reduced speed.
Otherwise, your vehicle may be damaged and/or
vehicle handling and performance may be ad-
versely affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
tire chains in such conditions can cause damage
to the various mechanisms of the vehicle due to
some overstress.

Do-it-yourself8-37

Some day-to-day and regular maintenance is es-
sential to maintain your vehicle good mechanical
condition, as well as its emissions and engine
performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
GENERAL MAINTENANCE
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
procedures regularly as prescribed.
Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer, a
NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this section are
required to be serviced at regular intervals. How-
ever under severe driving conditions, additional
or more frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and serviced. It is recommended that
you visit a NISSAN dealer for this service.
NISSAN technicians are well-trained specialists
and are kept up-to-date with the latest service
information through technical bulletins, service
tips and training programs. They are completely
qualified to work on NISSAN vehiclesbefore
work begins.
You can be confident that a NISSAN dealer’s
service department can perform the service
needed to meet the maintenance requirements
on your vehicle. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, it is
recommended that you visit a NISSAN dealer if
you think that repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” in the “Do-it-yourself” section of this
manual.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound in the “Do-it-
yourself” section of this manual.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links if necessary.
MAINTENANCE REQUIREMENTS GENERAL MAINTENANCE
9-2Maintenance and schedules

Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*:Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age. Wheel alignment and balance:
If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel
alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty In-
formation Booklet.
Windshield: Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming scheduled maintenance, cleaning the ve-
hicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor mat
away from the pedal. Brake pedal:
Check the pedal for smooth op-
eration. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, have your
vehicle checked immediately. It is recommended
that you visit a NISSAN dealer for this service.
Keep the floor mat away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Continuously Variable Transmission (CVT)
P (Park) position mechanism: On a fairly
steep hill check that the vehicle is held securely
with the shift lever in the P (Park) position without
applying any brakes.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment, it
is recommended that you visit a NISSAN dealer
for this service.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc., to ensure
they operate smoothly and all latches lock se-
curely in every position. Check that the head
restraints/headrests move up and down
smoothly and the locks (if so equipped) hold
securely in all latched positions.
Maintenance and schedules9-3

Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery* (for serviceable batteries): Check
the fluid level in each cell. The fluid should be at
the bottom of the filler opening. Vehicles oper-
ated in high temperatures or under severe condi-
tions require frequent checks of the battery fluid
level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.) .
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil to
drain back into the oil pan. Exhaust system:
Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected. It is recommended that you
visit a NISSAN dealer for this service. For addi-
tional information, refer to “Exhaust gas (carbon
monoxide)” in the “Starting and driving” section of
this manual.
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if fuel fumes are evident,
check for the cause and have it corrected imme-
diately.
Power steering fluid level* and lines: Check
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
9-4Maintenance and schedules

Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) for your vehicle.
For additional information, refer to “Mea-
surement of weights” in this section.
Also check tires for proper inflation pres-
sures. For additional information, refer to
“Tire and Loading Information label” in this
section.
LOADING TIPS
●The GVW must not exceed GVWR
or GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification
label.
● Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING
● Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could
cause personal injury.
● Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle can
break, tire damage could occur,
or it can change the way your
vehicle handles. This could result
in loss of control and cause per-
sonal injury.
● Overloading not only can shorten
the life of your vehicle and the
tire, but can also cause unsafe
vehicle handling and longer brak-
ing distances. This may cause a
premature tire failure which
could result in a serious accident
and personal injury. Failures
caused by overloading are not
covered by the vehicle’s warranty.MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the vehicle is loaded, drive
to a scale and weigh the front and the rear
wheels separately to determine axle
loads. Individual axle loads should not ex-
ceed either of the gross axle weight rat-
ings (GAWR) . The total of the axle loads
should not exceed the gross vehicle
weight rating (GVWR) . These ratings are
given on the vehicle certification label. If
weight ratings are exceeded, move or re-
move items to bring all weights below the
ratings.
